DIY site Curbly shows you how to replace a sink's p-trap, the most common source of annoying clogs.

A sink's p-trap is there to seal off the pipe with water to keep sewer gas that bypasses the vent from rising into your bathroom. Replacing your old p-trap should only take about 15-20 minutes for beginners, and the total cost for materials should be less than $20 if you have all the tools.

This is an excellent tutorial for novice plumbers, though I'm surprised the author doesn't focus more on cleaning the p-trap rather than replacing it outright. Any thoughts on that? Let us know in the comments. Thanks, Edgar!— Rick Broida
